rollup-standalone

0.42.9 verified Mon Apr 27 auth: no javascript deprecated

A standalone, browser-ready bundle of Rollup (v0.42.9), the JavaScript module bundler. This package provides Rollup as a single file with no external dependencies, suitable for use in browsers or environments without a module system. It wraps Rollup's API, allowing bundling without Node.js. Note that this is an older Rollup version (0.x), not compatible with modern Rollup plugins or configuration. The package is minimal with no recent updates.

Common errors

error rollup is not defined ↓

cause Trying to use a named import or require without proper bundler/ESM support.

fix

import rollup from 'rollup-standalone' // default import

error Cannot find module 'rollup' ↓

cause Mistakenly trying to import 'rollup' instead of 'rollup-standalone'.

fix

import rollup from 'rollup-standalone';

Warnings

gotcha The package wraps Rollup v0.42.9, which is very old. Modern Rollup plugins and configuration (e.g., using output.format) may not work. ↓

fix Use the official 'rollup' package instead, and ensure your configuration is compatible with Rollup 0.x.

deprecated This package is no longer maintained. Use the official 'rollup' package which offers a standalone build via unpkg or cdn. ↓

fix Switch to 'rollup' and use the official browser build from https://unpkg.com/rollup/dist/rollup.js

gotcha The default export is a function with methods; named exports do not exist. Developers may incorrectly try to import { rollup } or { watch }. ↓

fix Always use the default import: import rollup from 'rollup-standalone'

Install

npm install rollup-standalone

yarn add rollup-standalone

pnpm add rollup-standalone

Imports

rollup
wrong
```
const rollup = require('rollup-standalone');
```
correct
```
import rollup from 'rollup-standalone';
```
The package exports a single default function/object. ESM import is preferred, though CJS may work with bundlers.

rollup.watch

wrong

import { watch } from 'rollup-standalone';

correct

import rollup from 'rollup-standalone'; rollup.watch(options);

watch is a method on the default export, not a named export.

rollup.rollup

wrong

import { rollup } from 'rollup-standalone';

correct

import rollup from 'rollup-standalone'; const bundle = await rollup.rollup(inputOptions);

The build function is accessed as rollup.rollup (the default export is a function with methods).

Quickstart

Demonstrates building a module with rollup.standalone: creates a bundle and generates IIFE output.

// Basic usage: bundle a module
import rollup from 'rollup-standalone';

async function bundle() {
  const bundle = await rollup.rollup({ input: './src/main.js' });
  const { output } = await bundle.generate({ format: 'iife', name: 'MyBundle' });
  for (const chunk of output) {
    console.log(chunk.code);
  }
}

bundle().catch(err => console.error(err));
